排上村-75m以上岩层及地表移动与变形分析

Analysis of movement and deformation for rock seam above -75m level and ground surface at PaiShang Village

通过有限元方法对东乡铜矿排上村 -75 m以上岩层及地表移动与变形分析 ,得出尽管伴随顶板岩层崩落过程 ,地表会产生较大的移动、开裂和其他变形 ,但岩层崩落不会达到地表的结论 ,并通过实践证明给出的结论是正确的 .

A comprehensive analysis of the movement and deformation for rock seam above -75 m level and ground surface at PaiShang Village of DongShang Copper Mine by use of the finite element method has been carried out in this paper. The results manifest that even though the rock movement and crack as well as the ground surface subsidence take place as the rock in hanging wall falls down often while mining is in progress, but the ground surface collapse will never happen at the circumstance. These results are proven to be true by practice.
